Description

This application claims benefit of U.S. Provisional Application No. 60/620,336, filed Oct. 21, 2004, the contents of which are incorporated herein by reference. This application also claims benefit of priority under 35 U.S.C. § 119 to French Patent Application No. 04 08398, filed Jul. 29, 2004, the contents of which are also incorporated by reference.

Disclosed herein is a cosmetic composition comprising, in a non-fatty cosmetically acceptable medium, at least one water-dispersible linear sulfonic polyester and at least one nonionic thickening polymer. Also disclosed herein are processes using this composition. Further disclosed herein is a method for fixing a hairstyle comprising applying to hair a cosmetic composition comprising, in a non-fatty cosmetically acceptable medium, at least one water-dispersible linear sulfonic polyester and at least one nonionic thickening polymer.

Cosmetic compositions for shaping and/or holding the hairstyle may be in the form of spray compositions comprising a solution, which is generally alcoholic, and at least one component, known as a fixing component, which is generally chosen from polymer resins, the function of which is to form welds between the hairs or to coat the hairs. The fixing component is often formulated as a mixture with various cosmetic adjuvants.

These cosmetic compositions for shaping and/or holding the hairstyle are generally packaged either in a pump-dispenser bottle or in a suitable aerosol container pressurized using a propellant, the aerosol system comprising a liquid phase (or fluid) and a propellant. Styling compositions in a form chosen from gels, creams, and mousses may also be used.

Once such compositions are applied to the hair, it is intended that the fixing compounds therein will make it possible to fix the hair. However, the polymers commonly used as fixing agents in styling compositions do not allow the shape of the hairstyle to be maintained when the hair comes into contact with water for a prolonged period, for instance, when brought into contact with rain or perspiration or during bathing, for example, bathing in the sea or in a swimming pool, and the like.

The present inventors have discovered that the use of a cosmetic composition comprising, in a cosmetically acceptable medium, at least one water-dispersible linear sulfonic polyester and at least one nonionic thickening polymer, makes it possible to fix and/or shape the hairstyle and/or maintain the shape of the hairstyle when the hair comes into contact with water for a prolonged period. This phenomenon is referred to herein as “water resistance”.

As used herein, the term “prolonged period” means contact with water for a minimum period of one minute, for example, 10 minutes or 20 minutes.

The compositions of the present disclosure may also make it possible to obtain styling that is resistant to atmospheric moisture.

The compositions of the present disclosure may allow good fixing and/or good hold of the hair, i.e., a styling effect that lasts throughout the day, or even for several days, and/or shows good water resistance, such as good resistance to repeated bathing. These compositions may also have the advantage of being removed by shampooing. In addition, these compositions may also allow good cosmetic properties to be imparted to the hair.

Disclosed herein therefore is a cosmetic composition comprising, in a non-fatty cosmetically acceptable medium, at least one water-dispersible linear sulfonic polyester and at least one nonionic thickening polymer.

Also disclosed is a method for shaping and/or holding the hairstyle in which the cosmetic composition according to the present disclosure is applied to the hair.

Further disclosed herein is the use of a cosmetic composition comprising, in a non-fatty cosmetically acceptable medium, at least one water-dispersible linear sulfonic polyester and at least one nonionic thickening polymer, as a styling composition for fixing and/or holding the hair, for example, when it comes into contact with water for a prolonged period, i.e., in the case of rain, perspiration, or during bathing, such as bathing in the sea or in a swimming pool. According to this embodiment of the present disclosure, the use of the composition allows a water-resistant hairstyle (shaped hair) to be obtained, such that the fixing or hold of the hair is maintained after the hair comes into contact with water for a prolonged period.

The compositions disclosed herein may be in any form chosen from lotions, sprays, mousses, gels, creams, and pastes.

Other subjects, characteristics, aspects and advantages of the presently disclosed compositions and methods will emerge more clearly upon reading the description and the examples that follow.

As used herein, the term “styling cosmetic composition” means a composition for shaping or holding the hairstyle.

Other than in the examples, or where otherwise indicated, all numbers expressing quantities of ingredients, reaction conditions, and so forth used in the specification and claims are to be understood as being modified in all instances by the term “about.” Accordingly, unless indicated to the contrary, the numerical parameters set forth in the specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained by the present invention. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should be construed in light of the number of significant digits and ordinary rounding approaches.

Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the invention are approximations, unless otherwise indicated the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contain certain errors necessarily resulting from the standard deviation found in their respective testing measurements.

	Diglycol/CHDM/isophthalates/SIP copolymer	20
	(Eastman AQ 55 S - Eastman)
	Hydroxypropyl guar (JAGUAR HP 105 - Rhodia)	0.5
	Dimethicone (silicone oil)	1
	Stearyl alcohol	8
	Deionized water	qs 100
	Fragrance and ingredients	Qs

Eastman AQ 55 S sold by Eastman Chemical Company is a copolymer of diethylene glycol/1,4-cyclohexanedimethanol/isophthalate/sulfoisophthalate, and is a water-dispersible linear sulfonic polyester as defined herein.

Hydroxypropyl guar (JAGUAR HP 105—Rhodia) is a nonionic thickening polymer as defined herein.

Procedure:

Two grams of the test formulation were applied to a lock of 2.7 g of natural hair 27 cm long. The treated lock was rolled up on a curler 1 cm in diameter, to give it a shape. The product was left to dry in the open air and then the lock was removed delicately from the curler. The lock thus shaped was then immersed in a bath of 8 liters of salt water (3% NaCl) at room temperature, with magnetic stirring at 100 rpm. The length of the lock over time was measured in order to evaluate the shape hold. The results of the shape hold measurements are shown below in Table I. The shape hold was evaluated using the following formula:
% shape hold=(L_i−L)/(L_i−L₀)*100
wherein

• • L is the length of the curled lock at time t;
  • L₀ is the length of the curled lock after shaping and removal from the curler; and

L_i is the length of the lock before shaping on the curler.
